'DUMPiNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 228,655, dated June 8,1880.

Application filed March 13, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES S. LINTHIOUM, of Baltimore city, State ofMaryland, have invented certain new and useful Improvements inDumping-Vagons; and I hereby declare the same to be fully, clearly, andexactly described as follows, reference being had to the accompanyingdrawings, in which- Figure l is a side elevation of a wagon emro bodyingmy improvements; Fig. 2, a bottom plan of the same.

My invention has reference to dumpingwagons in general, and inparticular to that class of the same used for carrying coal and I 5adapted to discharge the coal into the cellarways of buildings anditconsists in a wagon of that class, constructed and operatingsubstantially as hereinafter set forth, the specific points of noveltybeing made the subjects of the claims.

In the accompanying drawings, A is the wagon-body, which is providedwith a bottom, a, hinged to the body at the rear lower edge, at a, andarranged to be lifted at its forward end by means of a chain, a, whichis led over a pulley, B, and thence to a drum, 0, which is mounted on ashaft, I, secured to the front of the body.

A suitable chute, f, is attached tothe end of the body, and may be suiiplemented, if desired, by a separate chute.

The wagon-body is provided with rollers D D, flanged, as shown, whichrest on the rearwardly-pitched bearers d d, between which 3 5 slide thesupplemental bearers G G, that are arranged to be drawn out rearwardly,as shown, and are provided with telescopic or equivalentverticallyadjustable legs g g. These are secured at any desired heightby catches or pins h. The rollers D are made sufficiently long to extendover the bearers and support the wagon-body thereon".

A chain, E, is led around apulley, (l, on the shaft I, and also around asecond pulley, F,

5 secured to the stationary bearers, and is hooked to a catch, 6, on thebody.

. The object of this construction and arrangement is to afford means forstarting the'wagonbody backward should it be necessary.

The shaft I is provided with square or polygonal shoulders c, and thepulley O and drum 0 are formed with correspondinglyshaped centralopenings, so that they may be readily thrown into and out of gear, asmay be desired. 5

In operation the wagon is backed up to the curb in front of thecoal-hole and the bearers G G are retracted, so that when the wagonbodyis run back thereon its spout will register with the coal-hole orcellar-Way, the vertically-adjustable legs g 9 serving to effect thisreadily. The wagon-body is then run back on the bearers, a suitablebraking mechanism being applied to the rollers in case the incline ofthe bearers be steep, and when the spout f is brought in proper relationto the cellarway the end gate is opened, and the contents of the cartfor the most part discharge themselves. Finally, the bottom a is liftedby means of the chain a, drum 0, and crank c, and the cart is completelyemptied. The body is then run back onto the bearers d, where it issuitably secured, and the bearers G G are pushed under the body andsecured.

The advantages of thedevice may be briefly set forth as follows: WVhileavoiding the manual labor incidental to the lifting of the body in thatclass of wagons which discharge the coal through chutes across thesidewalk, it dispenses with, the cumbrous and somewhat complicatedelevating mechanism, and substitutes for it the simple device fortilting the bottom. Besides, the coal may be discharged from my wagondirectly into the cellar in every case in which the wagon-body can bebrought to the coalhole, while it frequently happens with thechute-wagons that the extreme elevation of the body is not sufficient tocause the coal to run down the chutes.

What I claim is o 1. A dumping-wagon provided with a hinged bottom andmechanism for tilting it, as set forth, and one or more bearers arrangedto be retracted from beneath the body, whereby the end chute of thelatter is brought into communication with the place of deposit of thecontents of the wagon, as described.

2. In combination with the bearers (Z G G and vertically-adjustablesupports g g, the body A, having rollers D and tilting bottom a, as setforth.
